Description

Technical Field

[0001] The utility model relates to the field of inner lining plates for cement pipes, in particular to an inner lining plate for cement pipes dedicated to plastic machinery. Background Technique

[0002] The inner lining plate for cement pipes dedicated to plastic machinery is a specially designed plate, mainly used for the inner lining of cement pipes. Its main purpose is to enhance the durability, corrosion resistance and anti-aging performance of cement pipes, while ensuring the smoothness inside the pipes so that fluids can pass through smoothly.

[0003] This kind of inner lining plate is usually made of high-quality plastic materials, such as polyethylene (PE), polypropylene (PP), etc. These materials have excellent chemical stability, mechanical strength and wear resistance. During the production process, the inner lining plate will undergo precise processing and forming to ensure that it can closely fit on the inner wall of the cement pipe and has sufficient thickness and strength to withstand the pressure and fluid impact inside the pipe.

[0004] However, for the existing inner lining plates for cement pipes dedicated to plastic machinery, before being poured together with the cement pipe, the inner lining plate needs to be first rolled into a cylinder and welded. Due to the material reason of the inner lining plate itself, it has a certain elasticity. After being rolled into a cylinder, if it is not fixed with the help of external fixing equipment, the rolled inner lining plate will return to its original shape, thus affecting the welding.

[0005] Therefore, it is very necessary to invent an inner lining plate for cement pipes dedicated to plastic machinery. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides an inner lining plate for cement pipes dedicated to plastic machinery, including an inner lining plate. A clamping groove is formed on the circumferential surface at one end of the inner lining plate, and a plurality of clamping holes are evenly arranged in sequence on the end surface of the inner lining plate where the clamping groove is located. The clamping holes communicate with the clamping groove; the clamping holes are located at the center on one side of the clamping groove; a plurality of triangular clamping blocks corresponding to the clamping holes are fixedly installed in sequence at the other end of the inner lining plate, and the triangular clamping blocks are clamped in the clamping groove through the clamping holes.

[0007] Preferably, a plurality of T-shaped strips are fixedly installed on the outer surface of the inner lining plate, and a U-shaped cavity is formed between two adjacent T-shaped strips.

[0008] Preferably, a plurality of notches are evenly arranged on the transverse plates of the T-shaped strips.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The overall setting of the utility model enables the triangular clamping block to be clamped in the clamping groove through the clamping hole, so that the inner lining plate is rolled into a cylindrical shape. In this way, without the aid of external fixing equipment, the inner lining plate can always be in a cylindrical shape, effectively preventing the inner lining plate from self-resetting and unfolding, so that the operator can weld the connection part where the inner lining plate forms a cylinder, thus making the overall process more convenient and flexible. Brief Description of the Drawings

[0011] Figure 1 is a schematic diagram of the overall structure of the utility model rolled into a cylindrical shape.

[0012] Figure 2 is a schematic diagram of the overall structure of the utility model not rolled into a cylindrical shape.

[0013] Figure 3 is a partially enlarged schematic diagram of part A of the utility model.

[0018] Embodiment:

[0019] As shown in Figure 1 to Figure 3 shown:

[0020] The utility model provides a special cement pipe lining plate for plastic machinery, which includes a lining plate 1. A clamping groove 2 is formed on the circumferential surface at one end of the lining plate 1. Through the arrangement of the clamping groove 2, a clamping space can be provided for the triangular clamping block 4, so that after the triangular clamping block 4 enters the clamping groove 2, the whole can be made more flat. And a plurality of clamping holes 3 are evenly distributed in sequence on the end surface of the lining plate 1 where the clamping groove 2 is formed. Through the arrangement of the clamping holes 3, the triangular clamping block 4 can smoothly enter the clamping groove 2. The clamping hole 3 is communicated with the clamping groove 2; the clamping hole 3 is located at the center on one side of the clamping groove 2; a plurality of triangular clamping blocks 4 corresponding to the clamping holes 3 are fixedly installed in sequence at the other end of the lining plate 1.
